Abstract

Polyaniline-functionalized carbon nanotube (PANI-FNCNT) composite thin film was synthesized by the simple and inexpensive chemical bath deposition (CBD) method at room temperature in the presence of three different surfactants (Sodium dodecyl sulphate, cetrimonium bromide and Triton X-100) using ammonium peroxidisulphate (APS) as an oxidizing agent. The effect of the surfactant on the morphological, surface area and electrochemical properties of PANI-FNCNT composite thin film is studied. PANI-FNCNT composite with cetrimonium bromide revealed algae-like spongy morphology and showed a good surface area and porous structure. The electrochemical tests reveal the high specific capacitance of 1184 Fg-1 at a scan rate of 5 mVs-1 with 82 % capacitive retention after 5000 cycles and low charge transfer resistance.
